For enhanced safety, the front and rear seat shoulder belts of the Mercedes E-Class Sedan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chrysler 300 doesn’t offer pretensioners for the rear seat belts.
The E-Class Sedan’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 300 doesn’t offer pre-crash pretensioners.
Over 200 people are killed each year when backed over by motor vehicles. The E-Class Sedan offers an optional backup collision prevention system that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The 300 doesn’t offer backup collision prevention brakes.
The E-Class Sedan offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The 300 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The E-Class Sedan has a standard blind spot warning system, which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the 300 Touring L/S offers a blind spot warning system.
The E-Class Sedan’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The 300 doesn’t offer a driver alert monitor.
Both the E-Class Sedan and the 300 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available lane departure warning systems and rear cross-path warning.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mercedes E-Class Sedan is safer than the Chrysler 300:

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Mercedes E-Class Sedan is safer than the 300:

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the E-Class Sedan its highest rating: “Top Pick Plus” for 2019, a rating granted to only 113 vehicles tested by the IIHS. The 300 was not even a standard “Top Pick” for 2016.
